Customer's Distribution Panel Breaker Requirements
(Only When Connected to a Power Distribution Box)
This appendix describes the requirements for the breaker in the customer's distribution panel.
To protect the device when it is connected to the customer's distribution panel through a power
distribution box, the corresponding breaker in the customer's power distribution panel must meet
the following characteristic requirements so that the breaker of the device (or the power distribution
box) trips before the corresponding breaker in the customer's distribution panel. Use a breaker that
meets these requirements in the customer's distribution panel.
Power input
200 to 240 VAC
Use a long-time-delay type breaker whose characteristics correspond to phase D shown in Figure
A.1 Breaker characteristics (IEC898 or DIN0641 Part II). Alternatively, use a slower breaker.
